“…Pea phenology is controlled by daylength and temperature, with temperatures typically ranging between 6 and 268C in most pea growing regions (Alcade et al 2000). High daily maximum temperatures (31 to348C) during flowering for at least 2 to 4 d reduce pea yield (Karr et al 1959) via abortion of buds and flowers (Guilioni et al 1997), aborted young seed (Jeuffroy et al 1990), and potentially smaller seed (Lambert and Linck 1958;Jeuffroy et al 1990;Ney et al 1993;Poggio et al 2005). Not all of these yield components are significantly reduced in every stress study though.…”

“…Part of this effect could be due to water stress in the field. The literature contains a range of values from 318C to above 338C daytime temperature, lasting for 6 h per day, and usually imposed for 3 or more days in succession (Lambert and Linck 1958;Karr et al 1959;Ney et al 1994;Guilioni et al 1997). The most definitive studies are from growth chambers, but in single pots and at lower light irradiance ( B600 mmol m (2 s (1 ) than the field (1800 mmol m (2 s…”

Effect of heat and precipitation on pea yield and reproductive performance in the field

. 2015. Effect of heat and precipitation on pea yield and reproductive performance in the field. Can. J. Plant Sci. 95: 629Á639. Pea (Pisum sativum L.) is important globally as a cool season crop. Pea cultivars are heat-sensitive so our goal was to investigate how weather impacted growth and yield in recent cultivars in the Co-operative pea yield trials (2000 to 2009) for a dryland (Saskatoon) and an irrigated (Outlook) location. We explored relationships between days to maturity, days spent in reproductive growth (flowering to maturity), yield and various weather factors. Yield and the length of reproductive growth increased with seasonal precipitation. Pea was sensitive to heat but heat units did not satisfactorily describe growth and yield in all environments. Strong relationships were observed between crop growth and mean maximum daily temperature experienced during reproductive growth, and between crop growth and mean minimum temperature. The greater the mean maximum temperature (25.58C), the fewer the number of days (B35) spent in reproductive growth at the dryland location. At Outlook, 35 to 40 d in reproductive growth occurred in a much wider temperature range from 24.5 to 278C, and irrigation mitigated some reduction in yield. For dryland pea, more than 20 d in the season above 288C were associated with less time in reproductive growth and less yield. The threshold maximum temperature for yield reduction in the field was closer to 288C than 328C from published studies, and above 17.58C mean seasonal daily temperature. Western Canadian cultivars currently have short lifecycles, which make them heat sensitive. Heat tolerance could be improved by earlier flowering and a longer duration of flowering via an indeterminate habit. Future research will investigate pea nodal development, flowering and abortion patterns in a range of pea cultivars in field conditions.

Effets de la chaleur et des pre´cipitations sur le rendement du pois et sa performance a`la reproduction au champ. Can. J. Plant Sci. 95: 629Á639. Le pois (Pisum sativum L.) est une importante culture de saison froide dans le monde. Les varie´te´s de cette espe`ce e´tant sensibles a`la chaleur, les auteurs voulaient de´terminer l'impact des conditions me´te´orologiques sur la croissance et le rendement des plus re´cents cultivars pre´sente´s lors des essais coope´ratifs de 2000 a`2009 en milieu aride (Saskatoon) et sous irrigation (Outlook). À cette fin, ils ont examine´les liens entre le nombre de jours avant maturite´, la dure´e en jours de la croissance reproductive (de la floraison a`la maturite´), le rendement et plusieurs parame`tres climatiques. Le rendement et la dure´e de la croissance reproductive augmentent avec les pre´cipitations saisonnie`res. Bien que le pois soit sensible a`la chaleur, le nombre de degre´s-jours ne de´crit pas de manie`re satisfaisante sa croissance et son rendement dans tous les en...

“…Elevated temperature reduces seed yield in field pea (Lambert and Linck, 1958;Karr et al, 1959;Guilioni et al, 1997;Sadras et al, 2012;Bueckert et al, 2015) in two ways, by causing abortion of flowers and young pods, and by accelerating the crop lifecycle. Interestingly, the maximum temperature threshold affecting pea growth performance and yield formation under environmentally controlled conditions is higher than that threshold in the field.…”

“…No correlation was observed between ET efficiency and the other weather variables measured (Table 2). Heat and drought stress, particularly during flowering, have negative effects on seed yield (Lambert and Linck 1958;Maurer et al 1968;Pumphrey et al 1979;McDonald and Paulsen 1997). The efficiency of ET (dry matter basis) also decreases with increasing aridity (Tanner and Sinclair 1983).…”

[473][474][475][476]. Evapotranspiration (ET) efficiency regulates suitability and management of crops on the Canadian prairies. To evaluate the ET efficiency of pea (Pisum sativum L.), soil water depletion and yields as a function of precipitation were determined for Carneval pea at 28 sites in south and central Alberta from 1995 to 1998. Soil water depletion between seeding and harvest was as high as 112 mm at sites with high levels of available soil water at seeding and low to moderate levels of precipitation. Pea was capable of extracting soil water to a depth of about 0.6 m at most sites, but extraction of soil water below this depth was much more variable. At sites where soil water did not limit the depth of soil water extraction, a negative correlation was observed between the maximum depth of effective soil water extraction and the sum of maximum temperature degree-days above 25.6°C. The ET efficiency of pea seed yield ranged from 7.5 to 19.1 kg ha -1 mm -1 , with an average value of 13.0 kg ha -1 mm -1 . No correlation was observed between ET efficiency and weather variables, such as average temperature, vapor pressure deficit or length of the growing season.
